Hey! Sorry, I haven’t logged in on this account since I made this post. I would really appreciate it if you could share this with them. I am not comfortable doing so myself. Thanks!

I would trust the potency to not be a problem for the duration of the typical manufacturer recommendation of 3 years. That is if you follow storage instructions (cool, dark, and dry). Light and heat will especially be problems for decomposing estradiol esters. You can take the powder sublingually but you have to measure out 2 mg daily and make sure to get this extremely small amount under your tongue. If injections are a problem, you could get 17-beta-estradiol and make a gel that you just apply to your skin once or twice daily. Here’s a guide for that https://groups.io/g/MTFHRT/wiki/30843

Absolutely!

Once in solution you can store in a cool, dry, dark place and it should be good for 3 years. Powder should be stable for a lot longer though

I don’t see anything identifiable. Thanks for looking out though!

Just one sample haha. Was trying to do it quick to not to get fired. I’m not too worried about problems with homogeneity since the powder appeared to be that of a pure compound (fine, white powder).

Thanks! I don’t have access to an autoclave but tbh you don’t really need to even boil them. The benzyl alcohol will kill anything in the solution except the endospores. The autoclave kills bacterial spores IIRC from my microbiology course, but the risk is very low for IM injections (not an expert on this so look into it further if you’re worried). Boiling will NOT kill endospores, so IMO, there’s no difference between boiling and just using benzyl alcohol.
